PUMPING-MACHINE FOR STONE-SAWS.

SPECIFICATION forming part of Letters Patent No. 326,323, dated September 15, 1885.

Application filed March 31, 1885.

f all whom it may concern.-

"mont, have invented a new and Improved Pumping-Machine and Distributing Device for Stone-Sawing Machines, of which the following is a full, clear, and exact description. My invention relates to improvements in pumping-machines principally designed to be used in pumping a mixture of sand and water, and distributing the same, in connection with machines for sawing and finishing stone.

Heretofore in all the so-called sand-pumping machinery extra counter-shafts and driving-belts have been supplied to drive said pumping machinery, thereby using more machinery and power. This class of pumping or elevating machines has been found to be objectionable in use for the reason that they require a large outlay of power to drive the extra machinery before mentioned The sand and water have also heretofore been distributed over the stone to be sawed from a distributingboard in a fixed position, whether the stone was high or low. WVhen the stone to be sawed is low in the gang, the sand and water falling from the distributing-board which has been fixed high enough to admit large blocks cause great troublefrom spattering. It wastes the sand and water, annoys the sawyer, and injures the sawing machinery. It also requires more power to raise the sand and Water to this unnecessary height. Hence the importance of a movable distributing-board that can readily be adj ustedto any height of stone in the gang.

The object of my invention is to provide a pump and distributing apparatus of such constructionthat the sand and water may be regulated according to the amount required, which varies as the number of saws in the sawingmachine is larger or smaller, and also by the adjustable distributing board, which can be lowered in sawing low stone, and obviates the necessity of raising the sand and water any higher than each stone requires, thereby in both of theseways econoniizing the power, and said pump deriving its motion directly from the sawing-machine, thereby dispensing with all extra counter-shafts or other driving ma- (No model.)

chinery used in other so-called sand-pumping machines.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved pumping-machine and distributing device for stone-sawing machines. Fig. 2 is an enlarged side and sectional view of the pumping device. Fig. 3 is a top view of the same, parts being broken out. Fig. 4 is a sectional View of the vertical spout and its feeding device. Fig. 5 is'an enlarged side view of the devices for raising and lowering the spout.

A represents a block of stone in position to be sawed. 13 represents the gang'frame. U Uare blocks upon which the stone rests while being sawed. P P are posts, which support the overhead part of the sawingmachine and guide the gang-frame B. T represents the gang-bed. 0 represents the floor. I is the gangpitman connecting the crank wheel L with the gang-frame B.

The pump consistsof a vessel orcompartment, XV, provided at each end with an upwardly-projecting curved cylinder, w, in the top of which a flexible diaphragm, l, is securely clamped, which is connected by a connecting-rod, a, with a pin, a passed-through a longitudinal slot, h,'i11 one end of a rocking lever. g, pivoted on an upright frame, b, se-

cured to the supply-tank Y into which supply-tank fresh sand and water are conducted through the spout 00 from the sand-box M. A flanged neck, n, projects from each cylinder w into the compartment W, and is held in place by a toggle-lever, m, in the cylinder 10, and resting against a cross-piece, t, of the neck, thus preventing the neck from being forced into the cylinder 10. The inner end of the neck a is beveled, and a valve, 0, is hung on the same. From the tank Y 'a flanged neck, a, projects into each cylinder 20', which necks n are held in place by a toggle-lever, in, resting against the cross-pieces t of the said necks a, and preventing the necks a from being forced into the tank Y". The outer ends of the necks n are beveled, and on the beveled ends valves 0 are hinged, which open into the cylinders w. From the pivoted lever g a lever, W, projects upward, which is pro vided with a longitudinal slot through which a bolt passes, which also passes through a rod, K, connecting the said lever W with the pitman I. The pivots a in the lever g are connected by the rods 0 with the opposite ends of a lever, d, pivoted by the pivot f in the frame I) on the tank Y The material is discharged from the compartment W through the pipe Y, fitting on the necks r in the top of the said compartment. 1) is a hand-hole in the top of the compartment W. which is closed by a suitable valve. At U is a waste-outlet. The spout It runs from the gang-bed T to the receiving-tank Y for the purpose of conducting the used sand back to the receiving-tank, and S is an outlet for conducting off the waste sand and water.

0 represents one end ofa distributingboard, which may be of any desired pattern. D D are the straps by which it is suspended above the stone, and G is a small rope, one end of which is attached to one end of each of the straps D. and the other end iswound around a shaft, J, on which a grooved pulley, H, is keyed. V is a hand-rope, one end of which is wound on the rope-pulley H and the other end is secured to a cleat,V, on one end of the posts'P. G represents a small rope, one end of which is wound on the shaft J, and the other end is attached to the upper end of the vertical spout F, below which the funnel E is provided, into which the spout empties. The discharge-pipe Y, leading from the pump, empties into the vertical spout F.

The operation is as follows; The gang-frame is set in motion by means of the crank-shaft- L and the pitman I. By means of the connectingrod K the lever W and the cross-piece g are reciprocated, and thereby the flexible 'diaphragms Z are raised and lowered alternately. The freshsand box M is filled with sand and a small stream of water is conducted into the upper corner of the said box and washes aquantity of sand throughthe spout as into the receiving-tank Y. When the diaphragm at one end of the pump is raised, the mixture of sand and water is drawn from the tank into that cylinder 10 of the pump, the valve 0" being raised. Then as the corresponding dia phragm l is forced down the mixture of sand and water is forcedfrom that cylinder w into the compartment W up through the pipe Y and into the discharge-pipe F, from which it passes down through the funnel E and from:

the distributing-board 0 upon the stone which is being sawed. The sand and water then pass through the kerfs of the stone upon the gangbed, and flow down through the spout B into the receiving-tank Y, and so on until the sand is worn out, when it passes 011 with the water by overflowing the receivingtank Y, and then passes off through the water-drain S. When it becomes necessary to stop the pump, the waste-valve is opened, thereby allowing all the sand and water remaining in the pump to flow out, whereby settling of the sand and clogging of the machinery is prevented.

The operation of the distributing-board is that the operation of my pumping-machine is not dependent on any particular size or construction, for by placing the said pump above the pit it becomes a suction-pump and performs the work as well as in the position in which I have shown it placed in Fig. 1. Very little power is required to operate a pump ing-machine constructed in accordance'with my invention. Ample leverage is provided for workingthe rocker'arm and diaphragms, and they are thus rendered easy of operation.

I do not limit myself to any particular con struction of pump or location of same; neither do I limit myself to the particular connection with the gang herein shown anddescribed.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. The combination, with a stone-sawing gang, of a pump for raising sand and water and a rod for connection with and for operating the said pump from the gang or pitman,

substantially as herein shown and described 2. In a stone-sawing machine, the combination, with the adjustable distributing-board" O, of the funnel E and the vertical tube F, connected with the supply-pipe, substantially as herein shown and described.

3. In a stone=sawing machine, the combination, with the adjustable distributing-board 0 and the funnel E, of the vertical tube F,

emptying into said funnel, the rope G, suspending the said tube from the pulley-shaft J the pulley H on the said shaft, and the rope G, substantially as herein shown and described.
